Overview
If you get a new phone, change your phone number, or get a new device, you can update this information so you can continue to secure your account using MFA.
You can manage your devices via the NetID Center or the Duo Universal Prompt. You can find instructions on using either interface below.
- If you use the NetID Center, take a moment to make sure that your recovery information is up to date.
- If you are at a Duo Universal Prompt, you will need to select Other options to go to the authentication methods screen. On the next screen, select Manage devices and verify your identity.

Don't Have Your Device?
If your MFA devices are not available and you need to regain access to your account, you can get a temporary bypass code sent using your recovery information. Navigate to the Temporary passcode page and follow the instructions there.
If you need additional information, please visit: How do I generate and use MFA / 2FA temporary passcodes?.
- Bypass codes are meant to be used as a temporary means to access your account and can be requested 24 times per year.
- Each code can be used 100 times and expires after 3 days.
Duo Mobile App and Duo Push
The Duo Mobile app provides the ideal combination of security and convenience. The push notification function of the app is the preferred option to authenticate with MFA. The app is available in the Apple App Store (Duo Mobile App iTunes link) and the Google Play Store (Google Play Duo App link).
Additionally, Duo Mobile can be set up on tablets or other compatible devices that do not have a phone number.

NetID Center
Select the trash can button to delete a device.
Note: You may not remove your device if you only have one set up. If you wish to remove it, first add another then delete the original. You will be given a chance to confirm or cancel the removal of the device. Once the device is deleted, it can no longer be used to approve DUO requests.

Duo Universal Prompt

Note: The delete option will only appear if you have another device listed. If you wish to remove it, first add another then delete the original. You will be given a chance to confirm your selection.

You'll need to authenticate before you will be able to manage your devices. If you have another MFA device such as a hardware token you can use that, or you can send yourself a temporary passcode.
- If you do not have a recovery email address registered - or have access to that email address - you will need to contact your campus help desk.
- Once you're in, please update your recovery information via the NetID Center.
Instructions on how to use your temporary passcode can be found in this help article: How do I generate and use MFA / 2FA temporary passcodes?
Depending on which Duo Prompt you are seeing, the remembered devices feature will be referred to as one of the following:
- A prompt asking you 'Is this your device?'
- A checkbox with the label 'Remember me for 24 hours'
If you choose for Duo to remember you or trust your browser, a trusted session will be created for 24 hours between you, your browser, and the endpoint you are logging into. This involves using a browser cookie. If you have restrictive cookie settings in your browser, you may run into issues utilizing this feature. Visit
Can Duo's Remembered Devices feature work if third-party cookies are blocked? for more information.
Do not trust the browser when using a public or shared computer! This could leave your Duo session available to other individuals. Trust the browser only when you access applications from your own computer.
The screenshots below show how to enable the remembered devices feature so you can minimize the number of times you see the MFA prompt.
If you're authenticating with MFA for the first time in your browser, you will see the below screen after you authenticate:

Once the trusted session cookie expires (after 24 hours), you will see the below screen when authenticating. The remembered devices feature is enabled by default, but you can uncheck the checkbox shown below to disable it if desired:

NetID Center
If you authenticate with more than one device, you can specify the default by selecting the blue star icon:

You can also choose the default behavior when you authenticate via a UI Verify Duo Prompt:

Duo Universal Prompt
The first time you access the Duo Universal Prompt for a given application, it will evaluate your registered devices and automatically select the most secure option available to you, using this ordered preference (ordered from most to least secure):
- FIDO2 Security Key
- Duo Mobile push approval
- Yubikey passcode
- Duo Mobile generated passcode
- Hardware token passcode
If you want to try a different method than the one selected for you, you can select 'Other options' to get a list of your available authentication methods:

When you successfully authenticate, the Duo Universal Prompt remembers the authentication method used and defaults to that method for future logins to that application. If you want to try a different method than the one used last, select 'Other options' to get a list of your available authentication methods.
Automatic Duo Push
If you explicitly choose Duo Push authentication or it is automatically selected on your behalf during a first-time authentication, Duo will automatically send the push notification to your device without any action needed by you. During future authentications, Duo will continue to send the push notification automatically if that remains your default authentication method.
